[Limdep Nlogit List] Error in bootstrapping coefficients in Poisson Panel Model

[William Greene]

Derek. Version 8.0 did not have the capability to do this kind of
bootstrapping with panel data. That was new with 9.0. I believe this
will explain the diagnostic.

Subject: [Limdep Nlogit List] Error in bootstrapping coefficients in Poisson Panel Model

Hello all,

In trying to bootstrap the coefficient estimates in an unconditional
2-way Fixed Effects Poisson Model (with unbalanced panel), LIMDEP stops
after the first repetition with the following error messages and I
cannot figure out why:

Error   352: Model with Panel. Sum of T(i) not equal to full sample size
Error   498: Skipping  99 repetitions after error flag set.

A single run of the basic model works before I try bootstrapping. But
after trying bootstrapping and receiving the error message, any future
attempt to do a single run of the basic model also yields the above
error.

My commands are modelled on the example in the manual:

CALC		; vars = Col(xf) $
MATRIX	; bb = Init(vars,1,0.0)$
PROC		
 POISSON	; LHS = EXPORT  ; RHS = xf
		; Fem ; Pds=ni $
 MATRIX	; bb = b $
ENDPROC
EXEC		; Bootstrap=bb ; N=100 $

One last note: I am still working with Version 8.0
Any advice would be very much appreciated.
